Tools You'll Need:
* Phillips head screwdriver (possibly a flathead as well, depending on your specific S10)
* New taillight assembly (make sure you get the correct one for your truck's side – left or right)
Steps:
1. Prepare the Truck: Park your S10 on a level surface, engage the parking brake, and turn off the ignition.
2. Access the Taillight: Open the tailgate (if applicable) and locate the taillight assembly. You'll need to access it from the inside of the truck's bed or from the wheel well, depending on the design. Sometimes there's a small access panel in the bed itself.
3. Remove the Taillight: This is where things get a little specific to your S10. There are usually screws holding the taillight assembly in place. These screws might be accessible directly or you might need to remove some interior panels to get to them. Look closely around the edges of the taillight – you might see screw heads or clips.
* Screws: Carefully unscrew the screws (usually Phillips head) holding the taillight in place.
* Clips: Gently pry the taillight assembly away from the body. Work carefully to avoid breaking the clips. Start at one corner and work your way around. Often, a flathead screwdriver (carefully used) can help release stubborn clips.
4. Disconnect the Electrical Connector: Once the taillight assembly is loose, disconnect the electrical connector. This is usually a simple push-and-twist action. Gently pull the connector apart.
5. Install the New Taillight: Carefully install the new taillight assembly, aligning it with the mounting holes. Secure it with the screws or clips you removed earlier.
6. Reconnect the Electrical Connector: Reconnect the electrical connector. Make sure it clicks securely into place.
7. Test the Taillights: Turn on your taillights, brake lights, and turn signals to ensure the new taillight assembly is working correctly. If not, double-check all connections.
Important Notes:
* Consult a Repair Manual: A repair manual specific to your 1990 Chevy S10 will provide the most accurate instructions and diagrams. This is especially helpful if you're unsure about accessing the taillights or removing any interior panels.
* Take Pictures: Before disassembling anything, take pictures. This will help you remember how everything goes back together.
* Be Gentle: Avoid using excessive force when removing or installing the taillight assembly. You could easily damage the clips or the taillight itself.
If you're uncomfortable working on your vehicle yourself, it's always best to consult a qualified mechanic. This guide is for informational purposes only.
